Product details

Overview

CYPAS213A124SXQTXUMA1 from Infineon is an integrated secondary-side USB Power Delivery 3.1 controller with synchronous rectifier (SR) driver, supporting EPR up to 28 V VBUS, 300 kHz SR switching, and dual-mode feedback (CV/CC) via internal error amplifiers. It implements full protocol stack for USB PD 2.0/3.0/3.1, QC5.0–2.0, AFC, Apple Charging, and BC 1.2 in compact 32-pin QFN package for high-efficiency AC-DC flyback adapters.

For engineers reviewing the CYPAS213A124SXQTXUMA1 datasheet, CYPAS213A124SXQTXUMA1 pinout, CYPAS213A124SXQTXUMA1 application, or CYPAS213A124SXQTXUMA1 equivalent, key selection criteria include SR propagation delay (40 ns turn-on / 25 ns turn-off), integrated 32-bit Cortex® M0+ (64 KB Flash, 8 KB SRAM), dual VBUS discharge FETs, LSCSA with CSP/CSN inputs, and support for QR/CrCM/DCM/CCM topologies.

Technical Context

The device integrates a programmable MCU subsystem (Cortex® M0+, 64 KB Flash, 8 KB SRAM) that executes USB PD policy engine, SR timing control, and protection logic-including configurable OVP/UVP/OCP/SCP/OTP-while coordinating primary-side feedback via EA_OUT/FB across optoisolator or digital isolator barriers.

Its SR control architecture supports fast zero-crossing detection using SR_CAP input, false-turn-on suppression via differential sensing on SR_SEN/SR_CPP/SR_CPN, and gate drive compatibility with both standard and logic-level NFETs across all conduction modes up to 300 kHz.

Equivalent & Alternatives

The following parts are listed as comparable options for similar USB PD + synchronous rectification controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CYPD3177-24LQXQ	Legacy EZ-PD™ PAG1 device; no EPR support; max VBUS 20 V; lower SR frequency (200 kHz)	Limited to USB PD 3.0 standard power range (≤20 V); not suitable for 28 V EPR designs	Select only for cost-sensitive legacy PD 3.0 adapters where EPR is unnecessary
MPQ4282-AEC1	Monolithic DC-DC controller with integrated SR FETs; no USB PD stack; no MCU or CC interface	Targeted at fixed-output isolated converters-not USB-C negotiable power supplies	Choose only for non-USB-C, fixed-VOUT flyback designs requiring integrated power stage

Compared with CYPD3177-24LQXQ, CYPAS213A124SXQTXUMA1 adds EPR, higher SR frequency, and enhanced MCU resources; versus MPQ4282-AEC1, it provides full USB-C protocol stack and external SR FET flexibility-critical for scalable, field-upgradable adapter platforms.

FAQ

What USB Power Delivery versions and charging protocols does CYPAS213A124SXQTXUMA1 support?

CYPAS213A124SXQTXUMA1 supports USB PD 2.0, PD 3.0 with PPS, and PD 3.1 with Extended Power Range (EPR) up to 28 V. It also implements Qualcomm Quick Charge 5.0–2.0, Samsung AFC, Apple Charging, and Battery Charging (BC) 1.2 protocols-all executed on its integrated Cortex® M0+ core with firmware upgradability.

Does CYPAS213A124SXQTXUMA1 require an external microcontroller for USB PD negotiation?

No. The device integrates a fully functional 32-bit ARM Cortex® M0+ MCU with 64 KB Flash, 8 KB SRAM, and 64 KB ROM, running Infineon's certified USB PD stack. No external MCU is needed for PD negotiation, SR timing control, or protection logic execution.

What is the function of the SR_CAP pin, and why is it critical for ZCD accuracy?

The SR_CAP pin provides high-frequency sensing input for fast zero-crossing detection (ZCD), enabling precise SR turn-on timing during resonant valley switching. Its dedicated path minimizes propagation delay and avoids false triggering from primary-side ringing-critical for maintaining efficiency in QR and CrCM flyback topologies.

Can CYPAS213A124SXQTXUMA1 drive both standard and logic-level MOSFETs in synchronous rectification?

Yes. The SR_GDRV output is designed to drive either standard-threshold (≥4.5 V V_GS) or logic-level (≤2.5 V V_GS) NFETs. This flexibility allows optimization of conduction loss and gate drive loss across diverse adapter power levels and thermal constraints without redesigning the gate drive circuit.
